and Philip H. Elpiner, Euclid, Ohio, assignors to TransmarineCorporation, Chesterland, Ohio, a corporation of Ohio Filed Mar. 29,1965, Ser. No. 443,206 12 Claims. (Cl. 194-2) This invention relates toa payout drive assembly and circuit associated with a coin changedispensing apparatus, and more particularly to a unique rack and piniondrive payout assembly with a simple electrical control circuit therefor.

Heretofore, payout assemblies and associated electrical circuitry havebeen well known in the vending machine art. However, these payoutassemblies and circuitry have generally been utilized only for payingout small denominations of coins and for few coins. Hence, solenoidoperated payout assemblies have frequently been utilized, whereprecision operation, quiet and smooth efficiency, and a greatreliability were not essential features of the system. However, with thecoming of dollar bill changing apparatus, it becomes increasinglynecessary to pay out larger denominations of coins, as well as greaternumbers, so that the payout apparatus and associated electricalcircuitry must be extremely efiicient, yet simple and highly reliable.Systems proposed for this operation heretofore have been susceptible tojamming and have been cumbersome in design, noisy in operation and notparticularly reliable. Further, the electrical circuitry associated withsuch systems have been complex and expensive.

It is the general object of the present invention to avoid and overcomethe foregoing and other difficulties of and objections to proir artpractices by the provisions of a payout assembly and associatedcircuitry for a coin change dispensing apparatus which utilizes anessentially conventional coin storage magazine with a slide bar todispense the coins from the magazine wherein a plurality of parallelracks are operatively connected to the slide bar and driven at a uniformcontrollable rate to insure a smooth, non-binding movement of the slidebar to effect payout.

A further object of the invention is to provide a slide bar for payoutin a conventional coin storage magazine where a plurality of parallelracks are operatively connected to the slide bar which racks areindividually driven by pinion gears mounted to a common shaft and drivenby a reversible drive motor.

Another object of the invention is to provide a payout control circuitwhich utilizes snap action limit switches to limit the movement of theslide bar in both directions.

A further object of the invention is to provide a payout control circuitfor a double acting slide bar associated with a coin magazine storingcoins on both sides thereof which circuitry may drive a coin payoutslide bar for payout on one or both sides of the coin magazine accordingto the actuating denomination, and which circuitry is simple, highlyreliable, and requiring very few parts thereby eliminating expense.

A further object of the invention is to provide a payout drive assemblyand associated circuitry for coin change vending apparatus which isextremely simple, durable, inexpensive, and highly reliable.

The aforesaid objects of the invention and other objects which willbecome apparent as the description proceeds are achieved by providing ina coin change dispensing apparatus the combination of a horizontallypositioned base frame, a coin magazine having a bottom mounted in spacedrelation substantially the thickness of 3,280,953 Patented Oct. 25, 1966the coins stored therein, said magazine bottom removably mounted on thebase frame, a slide bar positioned in the spaced portion between thebottom and the magazine, parallel spaced rack means removably engagingthe bar, means to uniformly drive the rack means together in acontrolled reciprocating movement to cause the slide bar to push thecoins from their position between the bottom and the magazine, andelectrical circuit means to control the drive means to the rack meanswhich comprises a toggle switch actuated by the reception of a propercoin, a payout-drive motor actuated by the toggle switch for one waydrive, a first snap acting limit switch means actuated by the slide barto open the circuit to the drive motor to limit the one way movement ofthe slide bar, a toggle switch actuated by the opening of the limitswitch means to reverse the drive motor, and a second snap acting limitswitch means actuated by the slide bar to open the circuit to the drivemotor and to limit the opposite one way movement of the slide bar.

For a better understanding of the invention reference should be had tothe accompanying drawings wherein:

FIGURE 1 is a perspective view of the basic supporting frame andparallel rack and pinion drive apparatus associated therewith withoutthe coin storage magazine;

FIGURE 2 is a front plan view of the apparatus of FIGURE 1 with the coinstorage magazine in position;

FIGURE 3 is a side vertical cross sectional view taken on line 33 ofFIGURE 2;

FIGURE 4 is an enlarged broken away perspective view of the coin storagemagazine showing the relationship of the slide bar therewith;

FIGURE 5 is a schematic wiring diagram of the electrical circuit tooperate the drive mechanism shown in FIGURES 1 through 4;

FIGURE 6 is a schematic wiring diagram similar to FIGURE 5, but adaptedto only provide a single payout; and

FIGURE 7 is a schematic wiring diagram similar to FIGURE 5, but adaptedto only provide a double payout.

While it should be understood that this payout drive assembly andassociated circuitry might be utilized with any type of dispensing orvending payout desired, it is partcularliy adaptable to paying out coinchange for 25, 50 or dollar bills, and hence it has been so illustrated, and will be so described.

With reference to the form of the invention illustrated in FIGURE 1 ofthe drawings, the numeral 10: indicates generally a payout driveassembly which comprises a basic supporting frame 12 which supports anupper housing assembly, indicated generally by numeral 14, and ahorizontally positioned base frame 16. A coin receiving chute or bucket18 is operatively mounted to the frame 12 and positioned beneath thebase frame 16 so as to extend a considerable distance horizontally onboth sides thereof, as better seen in FIGURE 3, in order to receivecoins pushed out over both edges 20 and 22 of the base frame 16, as morefully described hereinafter.

In order to receive a coin storage magazine (not shown), the base frame16 has vertically directed end flanges 24 and 26 which, along with apivotally mounted top latch 28 removably interlock a coin storagemagazine in position on the base frame 16, all in substantiallyconventional manner.

As an important feature of the invention, a plurality of racks,indicated by numerals 30 and 32, are mounted in parallel relationship tothe frame 12 and the base frame 16 so as to be slidable relativethereto. Each rack is operatively driven by an associated pinion gear30a and 32a, which pinion gears are mounted in fixed relationship to asingle drive shaft 38. Each rack 30 and 32 has an elongated driver pin30b and 32b operatively affixed thereto, and extending through elongatedslots 30c and 32c in the base frame 16. As more fully describedhereinafter, the pins b and 32b drive a slide bar associated with thecoin storage magazine to discharge coins therefrom. Thus, it is seenthat rotation of the shaft 38 operatively drives the pins 30b and 32b ina controllably uniform relation along the slots 30c and 32c in the baseframe 16.

In order to accurately distinguish when the coins stored in a coinstorage magazine have reached the level for replenishment, and toprevent acceptance of coins or bills to actuate the apparatus, a triparm lever 40 along with associated circuitry 44 may be provided.

FIGURE 2 shows in schematic relation that a single motor may be used todrive the shaft 38. FIGURE 2 also shows a coin storage magazine 52 witha plurality of vertically extending coin chutes 54 operativelyassociated therewith. Each chute 54 is a substantially cylindrical borewith a small arcuate portion of the bore open to the face of themagazine 52, as clearly illustrated. The coins received in eachindividual bore 54 are stacked on top of each other and have a greaterdiameter than the open portion of each bore. from aluminum, and has acontoured milled base 56 which is positioned in spaced relationship fromthe body portion of the magazine 52 by means of a plurality of spacerwashers 58, positioned at the corners, as most clearly seen in FIGURE 4.Of course, it should be realized that suitable milling on the bottom ofthe body portion of the magazine 52 will accomplish the same purpose asmilling the base 56. The washers 58 may be held in position relative tothe base plate 56 and the body portion ofthe magazine 52 by suitablemeans such as screws 60, again as seen in FIGURE 4. The contour millingof the base plate 56, as well as the spaced relationship allows one coinin each chute 54 to be exposed to its full width, as more clearly seenby the coins, indicated generally by numeral 62 in FIGURE 2.

As discussed above, a slide bar 64 is received over the verticallyupwardly extending pins 30b and 32b, and is slidably received in thespaced portion between the base 56 and the body portion of the magazine52. The holes 7 receiving the pins in the slide bar 64 are only ofsufficient size to snugly position the slide bar thereover so that auniform movement of the pins will effect a uniform movement to the slidebar relative to the magazine 52 and the base frame 16. It should beunderstood that sliding movement of the slide bar 64 by pins 30b and 32bas actuated by the racks 30 and 32 will push each respective coin 62exposed in each respective chute 54 out and off the edge 20 of the base:frame 16 to be collected in the coin chute 18. With reference to FIGURE5, it can be seen that the coin storage, magazine 52 contains coinchutes 54 on both faces thereof so that movement of the slide bar 64either to the left or to the right will effect a coin discharge over theedge 20 or 22 of the base frame 16 and into the chute 18. FIGURE 3 alsomore clearly shows the relationship of the base 56 to the base frame 16and the coin storage magazine 52. It should be understood that the base56 will also have slots similar to the slots 30c and 32c in the baseframe 16 so that the pins 30b and 32b may slidably p ass relativethereto. It can also be seen with reference to FIGURE 3 that the slidebar 64 has sufficient width so that upon movement of the driver pins 30band 32b in either direction, the slide bar 64 will move to a position atleast flush with or slightly beyond the outer surface of the magazine52, thereby insuring that the coins expended fall over the edges 20 and22 of the base frame 16 and into the coin receiving chute 18. It mightbe also noted with reference to FIGURE 3, that suitable means, such asangle supports 70 and 72 secured by bolts 74 and 76, respectively, mightbe used to hold the base frame 16 in position relative to the main frame12.

In order to limit the movement of the racks 30 and 32 The magazine 52 isgenerally made and their respective drive pins 30b and 32b and to posi-'tively eliminate jack-potting of the payout, a pair of snap acting limitswitches or microswitches and 82, as seen in FIGURE 1, are positioned ateach side of the base frame 16 and mounted to the frame 12 by suitablemeans. A similar pair of switches are mounted on the opposite side ofthe frame, but are not seen in FIGURE 1 because of the perspective view.In order to effect operation of the switches 80 and 82, the pin 32b hasa downwardly extending portion 84 which will engage the arms 80a and 82aof the switches 80 and 82, as clearly shown in FIG- URE 1. The switches80 and 82 play an important part in the electrical control circuitry forthe payout drive assembly primarily to eliminate ja-ckpotting, as willbe more fully explained hereinafter.

In order to understand the electrical control circuit for the payoutdrive assembly, reference should be had to FIGURE 5 wherein a 110 voltsource drives into a pair of parallel positioned circuit lines 102 and104, respectively. The circuit contains four solenoids, indicatedgenerally by numerals 108, 110, 112 and 114, respectively. Plungers 108athrough 112a are shown in association with each of the solenoids 108through 112. The plunger 108a operates a single pole double throw relayswitch, indicated generally by the dotted box 116, through the dottedactuation line 108k. The plunger 110a operates a conventional doublethrow, single pole relay switch 118, as indicated by the dottedactuation line 11%. The plunger 112a operates a single pole double throwrelay switch, indicated generally by the dotted lines which controls thedirection of rotation of a motor indicated by the dotted lines 122. Thesingle pole double throw relay switches 116 and 120 are of the typewhich could conveniently be called toggle switches as they snap from onecontact to the other upon actuation and remain at the contact to whichthey have been moved upon deactuation. Whereas, the conventional doublethrow, single pole relay switch 118 snaps to a closed position uponactuation thereby deactuating the blockout solenoid 114, but snaps backto an open or prevent position upon actuation. The blockout solenoid 114may be utilized to control a plunger (not shown) to prevent insertion ofany denomination of money during the operation of the circuit, or whenthe power is off, all in a well known manner.

In order to eliminate acceptance of coins when the magazine is empty anout of coin switch, indicated -by the .dotted line 106 is provided inthe blockout circuit in a normally closed position, as indicated bysolid line 106a. When the coin magazine is empty the switch is moved tothe open position, indicated by dotted line 106b to deactuate theblockout circuit.

In order to provide for possible jamming overloads in the circuit, asubstantially conventional thermal cut-out, indicated by the dottedblock 122, may be provided. In order to simulate the snap acting limitswitches 80 and 82 in FIGURE 1, dotted blocks 124 and 126 labeled snapswi ches, are shown in the schematic diagram. This particular circuithas been drawn as illustrating payouts for a 25 insertion, actuating a25 switch indicated by block 128, and a 50 payout which is actuated by a50 switch indicated by dotted block 130.

It should be understood before beginning a description of the operationof the circuit of FIGURE 5 that the snap switches 124 and 126 are thetype which are normally in one position, and require external physicalactuation to switch, but automatically switch back to the normalposition when the external physical actuation is removed. Thus, thesolid lines 136 and 142 illustrate the usual positions for both switcheswhile the dotted lines 138 and 140 illustrate positions actuated by the.slide bar as driven by the motor 122. i

In operation of the circuit with a 25 coin inserted, the 25 switch 128closes thereby actuating solenoid 108 to drive plunger 108a to switchthe relay 116 from a solid line position 132 to a dotted line position134. This then completes the circuit for the solenoid 110 which throughplunger 110a actuates the switch 118 to open the circuit to the blockoutsolenoid 114 and prevent the insertion of any further coins until thecircuit has been completed. Simultaneously with the above describedelectrical occurrences, the circuit to the motor 122 has been completedby the movement of the relay 116 to the dotted line position 134 so thatthe motor drives in one direction until it engages the actuating arm ofthe snap switch 124 which shifts the switch 124 from its initialposition indicated by the solid line 136 to the dotted line position138, thereby opening the circuit to the motor and completing the cycle.It should be noted that the solenoid 112 is aso actuated as soon as the25 switch 128 is closed which, actuating through plunger 112a,immediately reverses the direction of rotation through motor 22 byshifting the arm in relay 120. Thus, upon deposit of another 25 pieceinto the apparatus, the motor 122 will reverse and the same sequence setforth above will take place except that payout will be effected by theslide bar pushing the coins out on the opposite side of the coinmagazine, as more fully set forth above. Thus, it is seen that thecircuit automatically drives the motor 122 in one direction or the otherupon actuation by 25 coin to effect the desired one cycle movement ofthe motor to achieve payout.

An additional purpose of the circuit is to achieve a two cycle movementof the motor 22 (in other words, in one direction and then back to theoriginal starting position) upon actuation of the switch 130 by a 50coin insertion. To this end when the switch 130 closes, it immediatelyactuates the solenoid 112 to drive the plunger 112a and actuate switch120 to drive the motor 122 in the opposite direction to achieve thefirst payout.

At the same time as solenoid 112 is actuated, the motor 122 is actuatedthrough either snap switch 124 or 126 since one of the switches 124 or126 must be in the normal position indicated by solid lines 136 and 142land the other switch must be in the forced closed position indicated bydotted lines 138 and 140. Suppose that switch 124 is in the normalposition indicated by solid line 136 while switch 126 is in the actuatedposition indicated by dotted line 140. However, as the motor 122 beginsto drive the switch 126 is released to its normal position indicated bysolid line 142. About the time switch 126 changes the switch 130 hasopened again after a momentary built in delay caused by the coin passedtherethrough. When this occurs the power supply to the motor 122 shiftsthrough solid arm 132 of switch 116 and through the shifted arm 142 asseen by tracing the circuit.

When the motor 122 drives to the end of the first payout it actuatesswitch 124 from its normal position indicated by solid line 136 to thedoted line position 138. The power actuating the solenoid 112 isactuated again causing it to effectively actuate switch 120 to reversethe mot-or 122 which is still receiving power through its previoussupply circuit. Of course, after the second payout is achieved theswitch 126 is actuated to the dotted line position 140 to break thepower supply circuit to the motor 122.

It should be understood that this circuit will operate substantially thesame except in an opposite mannerif the slide bar has been left after a25 payout in the opp-osite initial position, from that described above.Also, the circuit will operate in this manner described above regardlessof the position of the positive acting toggle switch 116 because of aprevious 25 payout.

Of course the blockout coil 110 is actuated in the same manner each timeto prevent coin insertion during payout.

Thus, it is seen that the unique aspect of this circuit is achieved byutilizing the single pole double throw switches 116 and 120 incombination with the snap acting limit switches 124 and 126 to achieve asingle payout when actuated by a 25 coin denomination, and a doublepayout when actuated by a 50 coin denomination. The solenoid 110 alwaysacts to deactuate the blockout solenoid 114 when the circuit has beenactuated by either a 25 or 50 coin. The thermal overload 122 controlsthe amount of current flow and circuit time operation to prevent darnageto the circuit. The relays 116 and 120 always snap to an oppositecontact upon actuation and remain at that contact after actuation.Conversely, the snap switches 124 and 126 snap to a normal positionunless actuated externally by the slide bar as driven by the motor 122thereby eliminating jackpotting of the circuit, whereas the switch 118snaps to an open position upon actuation and then closes again upondeactuation.

FIGURE 6 discloses a circuit diagram for only a single payout which issubstantially the same as FIGURE 5 except that solenoid 108, relayswitch 116, and switch 128 have been eliminated from the circuit. Toprovide a completion of the modified circuit the snap switches 124a and126a are not connected at their common center poles, but rather thecenter pole 1261) of switch 126a is connected to the downward pole 1246of switch 124a. To fully complete the proper current path necessary foroperation the downward pole 1266' of switch 126a is connected to theother line 102a of the circuit. One more important change completes thecircuit and this resides in switch 124a being switched so that in itsnormal position (i.e. not actuated by the slide bar driven by the motor)it is in the same downward position indicated by solid line 136a asswitch 126a also normally downward as indicated by solid line 142a. Thiseffectively completes the circuit to line 102a when neither switch 124anor 126a are actuated. Either switch 124a or 126a will be shifted to thedotted line position 138a or 140a. Naturally the coin receiving switch130a would have to be a delay type, as discussed with reference toswitch 130 in FIGURE 5, so the motor 122a might properly reverse anddrive away from whichever switch 124a or 126a was closed by the slidebar to allow actuation of the alternate power source before such switch130a opened.

FIGURE 7 discloses a circuit digaram for only a double payout which issubstantially the same as FIGURE 5, except again that solenoid 108,relay switch 116 and coin actuated switch 128 have been eliminated fromthe circuit. To provide a completion of the modified circuit the snapswitches 124d and 126d are connected at their common center poles 124eand 126e while the lower terminal 124 of switch 124d is connected to theother line 1021;. In this situation the slide bar must always start froma position actuating switch 124d to the dotted line position 1381; sothat it will snap to the solid line position 136b to provide analternate power source. The switch of the motor 122b will occur whenswitch 126d is actuated momentarily breaking the circuit to solenoid112a. Of course, power to the motor is terminated when switch 124d isagain actuated to the dotted line position 138b on the return of theslide bar to its original position. Naturally, the switch 13% receivingthe 50 coin must be the delay tape as more fully described above.

Thus, it should be seen that the circuits of FIGURES 6 and 7 providesimple modifications to the basic circuit of FIGURE 5 to provide onlysingle and double payouts respectively. And a particular feature of eachmodification is that both eliminate the solenoid 108, relay switch 116and coin actuated switch 128 thus providing a simple, inexpensivemodification as desired.

A simple circuit providing great reliability, and yet low cost has beenshown to achieve a single or double payout as desired. While this systemhas been utilized as showing payout for 25 and 50 denominations, itshould be understood that any suitable denominations of coins or paperbills could 'be utilized. If paper bills were used their properauthentication would provide signals to actuate the respective switches128 and 130.

Thus, it is seen that the objects of the invention have been achieved byproviding a payout drive assembly with associated circuitry whichutilizes a rack and pinion drive for a slide bar in a double sided coinstorage magazine to achieve a parallel, controllable and uniform movement to the slide bar so that payout may be effected on both sides ofthe coin storage magazine, with the associated circuitry accurately andreliably controlling the movement of the slide bar through a drive motorto effect a single, one directional movement of the slide bar to effecta single payout, with a return of the slide bar to the other side of themagazine to effect a double payout.
